Abstract: A process is disclosed for the decarburization of a molten bath of chromium-containing pig iron which, in a single operation, permits decarburization by means of an oxygen jet and thus permits chromium or nickel chromium steels to be obtained directly, the decarburization of which can readily be completed by a final treatment under vacuum carried out immediately after the injection of oxygen. The process comprises adjusting the temperature conditions of the pig iron bath and regulating the oxygen jet distance from the surface of the bath and speed of oxygen gas so that the impact force of the oxygen creates a gas-metal emulsion within which the carbon contained in the pig iron is oxidized directly by the oxygen. The carbon content is thus rapidly reduced to less than 0.3% whereas the yield of chromium is higher than 97%. The process is suitable for the preparation of all grades of Cr and NiCr stainless steel, which optionally contain additions of Co, Mn or Mo.

Abstract: REFRIGERATING MACHINE INCLUDING ENERGY   CONSERVING HEAT EXCHANGE APPARATUS                 ABSTRACT OF THE DISCLOSURE         An improved commercial cube/crushed ice making machine includes a refrigeration unit having a water-to-refrigerant heat exchange condenser operatively connectible to an external water supply for heating water therein.  The condenser provides for improved efficiency in the refrigeration unit over a conventional air-cooled condenser.  Also, the water heating capability of the ice-making machine preferably functions as a secondary heat source for the external water supply, thus providing savings in energy costs for the primary water heating source.  Further, the heat exchange relation between the refrigeration unit and the external water supply is determined by an improved control system which is responsive to both a refrigerant pressure at the condenser refrigerant outlet, and the water tempera-ture at the condenser water outlet for controlling water flow through the condenser while maintaining a pre-determined refrigerant pressure in the heat exchange means.

Abstract: ABSTRACT     Apparatus for determining the deterioration of components subject to variable operation conditions particularly helicopter gears subject to variable torque.  A monitor provides an analogue signal of the level of operating parameter which is passed through a conditioning device including a pre-amplifier, filter stage, multiplexer and analogue to digital converter.  A memory stores deterioration data for the component and a microprocessor repeatedly samples the monitored level of the parameter and determines the deterioration in successive time intervals.  An electromechanical counter provides a cumulative output of the deterioration of the components.  The microprocessor also analyses the parameter levels into ranges or bands and the total time each component is operating in each range is stored and printed out.

Abstract: ABSTRACT   A rotary chip carrier transport system (12) for transporting semi-conductor chips contained within chip carriers (14) through a wire bonding operation includes a final adjustment mechanism for advancing the chip carrier (14) after a transport drive motor (124) has been stopped at a predetermined position.  The driving motor (124) drives a transport system (12) in a first direction thereby causing gears in the gear train to wear on the driving side (150) of the gear teeth.  Thus, the position of the chip carrier (14) with respect to the position of the driving motor varies as the gears wear down. The final adjustment is accomplished by using an air driven piston to drive a clutch (40, 48) which in turn drives a shaft (26) that is rigidly connected to a positioning platform (70).  This action causes two gears (60, 108) to engage on non-driving side (152) of a pair of gear teeth, thus precisely posi-tioning the chip carrier (14).  Thus the chip carrier (14) is precisely posi-tioned without the necessity of special gears or an extra set of gears.

Abstract: Abstract of the Disclosure A chain saw guide bar assembly (30) having improved automatic chain tensioning, vibration damping and lubrication properties, and related lubrication methods are disclosed.  A nose guide member (34) rotatably carrying an idler sprocket (34.1) is mounted to an elongate primary guide bar member (32) for reciprocal longitudinal movement relative thereto.  Biasing spring members (50, 51), acting on force-imparting surfaces (60.4, 60.5), are protectively enclosed within an internal cavity (33) of the primary guide member and bias the nose guide member with predetermined tensioning force in the longitudinal direction against an endless cutting chain (40).  An interchangeable force block member (60) enables preselection of the desired chain tension force. Damping finger members (32.35, 32.36, 50, 51) cooperatively absorb vibratory forces transmitted through the guide bar.  Oil passageways (32.33, 32.34, 39) longitudinally extend through the guide bar to provide complete lubrication of the biasing means, the idler sprocket and other moving parts of the bar assembly and to provide improved lubrication of the cutting chain at a position adjacent the juncture of the two guide members comprising the bifurcated guide bar.  Method steps for lubricating the cutting chain and the idler sprocket from oil transmitted through the length of the guide bar are also disclosed.

Abstract: Abstract of the Disclosure An improved fastener has a head section and an axially extending shank section.  A thread convolution is disposed in a coaxial relationship with the head and shank sections.  An improved holding action against rotational and axial movement of the fastener relative to a metal base member is promoted by a plurality of radially extending wedge-shaped compression ramps.  The compression ramps are disposed on the head section and slope radially and axially inwardly toward the shank section.  The compression ramps are effective to force metal of the base member into an annular groove which circumscribes and undercuts at least a portion of the shank section.  The metal which is received in the undercut portion of the groove is effective to hold the fastener against being pushed or pulled axially outwardly from the base member.          The compression ramps also force the metal of the base member radially inwardly against corners formed on the shank section of the fastener to hold the fastener against rotation.  In addition, the compression ramps are embedded in the base member to further hold the fastener against rotation relative to the base member.  The compression ramps are separated by flat arcuate stop surface areas which limit the extent to which the fastener is pressed into the base member.

The model for  each process component includes a logic variable, which logic  variable can have only two values, 0  and  1, and  which represent  the run  or idle  status of  each process component.   The computer,  when predetermined conditions  arise, solves a mixed integer equation to determine the  optimum state of the process at a given time to produce the desired outputs, at desired rates and at minimum cost; and,  in doing so,  determines the value  of the logic  variable for each component.  When  a change of status of a  process component from run to idle  or idle to  run is required to  place the process  in its optimum state,  control  signals  to  cause  such  change  of  status  of  process components are applied to such components.

Abstract: ABSTRACT OF THE DISCLOSURE      A novel optically active diamide derivative repre-sented by the following general formula is provided, which is useful as a starting material for asymmetric synthesis of optically active compounds,   wherein: R1 is an acyclic or cyclic, divalent atomic group containing at least one carbon atom  which will, upon substitution of one of the heterocyclic groups in the formula with a nucleophilic reagent, stand as an asymmetric center in the substitution product; R2 is a substituent which has such a configuration and a molecular size that the regioselectivity in the substitution reaction of the heterocyclic group with the nucleophilic reagent can be determined by a stereo-chemical interaction thereof with the substituent R1, the steric configuration of the two asymmetric carbon atoms to which the R2 substituents are attached being identical; X is a sulfur atom or an oxygen atom; and n is an integer which is 1 or 2.  Such a diamide derivative can be prepared by subjecting the corresponding dicarboxylic acid or an anhydride thereof with the corresponding heterocyclic compound to condensation reaction in the presence of a condensation agent.    The optically-active diamide derivative can be used in the reaction with a nucleophilic reagent to obtain an optically-active compound.  The resulting compound can be further modified by subjecting it to reaction with other nucleophilic reagent or to hydroly-sis.
